3D WEAVING POSSIBILITIES ON AN 8 SHAFT LOOM
Full text linkThis work’s focus is towards exploring the possibilities of weaving select type of 3D reinforcements on the commercially available 2D weaving looms of the textile industry. In this context, two classes of 3D reinforcements were developed using 6K Carbon rovings of 400 Texon an 8 shaft handloom. The first class comprised of weaving single layer profiles wherein, ‘T’and ‘p’ profiles were woven. The second class comprised of weaving planar multilayer (angle
interlock structure) samples of two types viz., layer to layer and through-thickness. In this class, a ‘T’ profile was also woven. Weave Design Plan for these structures were developed using the warp(for single layer profiles) and weft ( for angle interlock structures) yarn cross-sections. It has finally been inferred that, woven cloth construction design and 2D weaving technology can be successfully utilized to develop select class of 3D reinforcements for composite applications
Type−directed weaving of aspects for polymorphically typed functional languages
Full text linkIncorporating aspect-oriented paradigm to a polymorphically typed functional
language enables the declaration of type-scoped advice, in which the
effect of an aspect can be harnessed by introducing possibly polymorphic
type constraints to the aspect. The amalgamation of aspect orientation and
functional programming enables quick behavioral adaption of functions, clear
separation of concerns and expressive type-directed programming. However,
proper static weaving of aspects in polymorphic languages with a type-erasure
semantics remains a challenge. In this paper, we describe a type-directed
static weaving strategy, as well as its implementation, that supports
static type inference and static weaving of programs written in an aspect-oriented
polymorphically typed functional language, AspectFun. We show
examples of type-scoped advice, identify the challenges faced with compile-time
weaving in the presence of type-scoped advice, and demonstrate how
various advanced aspect features can be handled by our techniques. Lastly,
we prove the correctness of the static weaving strategy with respect to the
operational semantics of AspectFun
The Maximal Intensity Period: Rationalising its Use in Team Sports Practice
Full text linkQuantifying the highest intensity of competition (the maximal intensity period [MIP]) for varying durations in team sports has been used to identify training targets to inform the preparation of players. However, its usefulness has recently been questioned since it may still underestimate the training intensity required to produce specific physiological adaptations. Within this conceptual review, we aimed to: (i) describe the methods used to determine the MIP; (ii) compare the data obtained using MIP or whole-match analysis, considering the influence of different contextual factors; (iii) rationalise the use of the MIP in team sports practice and (iv) provide limitations and future directions in the area. Different methods are used to determine the MIP, with MIP values far greater than those derived from averaging across the whole match, although they could be affected by contextual factors that should be considered in practice. Additionally, while the MIP might be utilised during sport-specific drills, it is inappropriate to inform the intensity of interval-based, repeated sprint and linear speed training modes. Lastly, MIP does not consider any variable of internal load, a major limitation when informing training practice. In conclusion, practitioners should be aware of the potential use or misuse of the MIP

Weaving aspects into web service orchestrations
Full text linkWeb Service orchestration engines need to be more
open to enable the addition of new behaviours into
service-based applications. In this paper, we illus-
trate how, in a BPEL engine with aspect-weaving ca-
pabilities, a process-driven application based on the
Google Web Service can be dynamically adapted with
new behaviours and hot-fixed to meet unforeseen post-
deployment requirements. Business processes (the ap-
plication skeletons) can be enriched with additional fea-
tures such as debugging, execution monitoring, or an
application-specific GUI.
Dynamic aspects are also used on the processes
themselves to tackle the problem of hot-fixes to long
running processes. In this manner, composing a Web
Service ’on-the-fly’ means weaving its choreography in-
terface into the business process
Weaving Community to Rebuild Social Trust
No full textSocial trust starts in our neighborhoods. It is the faith that people will see each other, act with a sense of shared humanity, and do what they ought to do. This past year showed how much our trust in each other has eroded, with a bitter election, an unchecked pandemic, rising and unequal economic pain and overdue demands for racial justice. As we look to rebuild social trust so our nation can move forward, where do we start? How do we help our neighborhoods and local institutions more deeply understand one another and strengthen their connections? This workshop explored ways for weaving communities and building bridges of trust as we chart a path ahead

Multiaxial three-dimensional (3-D) circular weaving and multiaxial 3-D circular woven preforms for composite
No full textNATO Advanced Research Workshop on Multilayered and Fibre-Reinforced Composites - Problems and Prospects -- JUN 02-06, 1997 -- KIEV, UKRAINEThis paper reviews multiaxial 3-D circular weaving and preforms for composite applications and presents the development of a new method for producing multiaxial 3-D circular preforms capable of orienting fibers along five axes. The yarn orientation along five axes provides good mechanical properties to the preform. In-plane properties of the multiaxial 3-D circular woven preform may be improved compared to the state of the art 3-D circular woven preforms. Also, the classification scheme of 3-D circular weaving is introduced according to yarn orientations in the structure.NAT
Maintenance of polymorphism in the orb weaving spider species Agalenatea redii (Araneae, Araneidae)
Full text linkThe maintenance of polymorphism within populations may be the consequence of several elements of species life history such as use of space, activity rhythms, predation, parasitism and reproduction. The present study focuses on the latter aspect using an orb weaving spider, Agalenatea redii, which presents five different morphs of the opisthosoma pattern in the adult stage. Over the course of four years, from 2008 to 2011, adult spiders (males, females and pairs) were observed at different sites. In 2011, we also conducted a six-week survey of a single population, observing the number of spiders of each morph and the morph of paired spiders. We collected field data on the spatial and temporal distribution of spiders based on their sex and morph. Using a distance analysis, we compared the field distribution with a simulated one in which pairs were associated at random. The results showed that although there were changes over time and space in the proportions of females of the different morphs, as well as in the proportion of the pair associations, pairing according to morphs probably occurs at random
